Installation Of Wireless Camera Surveillance At Building Entrances And Exits
Dec 04, 2022
Selection of installation mode and lens adjustment of building entrance and exit wireless camera surveillance:
1. Indoor installation:
Most of the traditional ways are to install the wireless camera surveillance at the entrance and exit of the building indoors. The advantage of this method is that the monitoring direction can be selected for installation (the consistency and closure of the monitoring direction should be considered in the same building to ensure that any person entering the building can leave a positive face image at a certain entrance). At the same time, this method is simple in installation, wiring and maintenance. It should be noted that the influence of outdoor light source on the wireless camera surveillance should be considered in the selection and installation position of the wireless camera surveillance. If the field of view of the monitoring camera is installed outdoors, the wireless camera surveillance with automatic aperture and strong backlight compensation should be selected. For the entrance and exit of complex lighting environment, wide dynamic camera, strong light suppression wireless camera surveillance and even additional light source should be selected.
2. Outdoor installation:
Install the vertical pole outdoors or install the wireless camera surveillance according to the attached body, and use the front camera or side camera to capture the image of the entrance and exit. This method has been gradually accepted and adopted, and has achieved good imaging results. The advantage of this method is that the outdoor natural light environment in the daytime has sufficient facial lighting, and the facial image is real and hierarchical, which can capture more details of human characteristics. The environmental lighting at the entrance and exit at night is single, and a satisfactory night portrait can also be obtained under the condition of sufficient environmental lighting. In this installation mode, low illumination wireless camera surveillance or ordinary illumination wireless camera surveillance can be selected according to the ambient illumination at night. The disadvantages of this installation method are that the installation location is limited by the landscape, and the wiring is a little troublesome. Some projects need to involve cutting the pavement, and the outdoor landscape environment needs to be considered. Some building entrances and exits cannot use this method due to environmental restrictions.
If the building environment allows, it is recommended to give priority to outdoor installation mode, and do a good job of outdoor lighting at night.
